Hi K.,
I have another idea. Magnesium. Low cellular magnesium can cause, irritability and aggitation, it can cause bladder issues, and it also is responsible for the contraction of muscles.
I have a boy who peed his bed, almost nightly, between 4-8. One thing that I read about was that pasturized milk before sleeping causes peeing the bed. I have put that to the test, and indeed, milk before bed causes him to pee his bed! Milk has 8 parts calcium to 1 part magnesium. When too much calcium is consumed, it pulls magnesium out of the body parts in order to assimilate it. Magnesium counters calcium and plays an important role in nero/muscular contractions. Low magnesium affects mucosal tissue in bladder, lungs,throat, ears ,sinus and vagina.
Since only 1% of our bodily magnesium is found in the blood- a blood test will not truly detect a cellular magnesium deficit. Magnesium deficiency can easily occur- it is estimated 80% are deficienct and 20% have an intake less than half of the USDA, which may itself be low to begin with. I have read that magnesium deficient pregnant mums pass the deficit to their offspring. Ingesting SOY can affect magnesium levels. Soy is a leading additive in our food supply now.
urge incontinence is helped by magnesium.
Taking magnesium internally can be an issue because one, it can cause diarrhea, and two, some people don't absorb it too well in the gut. Transdermal magnesium solves these problems and is easy to administer. Everyday, put magnesium oil (found online)on the skin. Magnesium oil is simply magnesium chloride in water. You can also give epsom salt foot baths for a half hour. The other option is a drinkable product called Nature Calm, which is magnesium citrate in water. I have never used Natural Calm so I don't know if it causes the runs or not.
I have read that it takes 3-6 months to bring cellular magnesium levels up to optimum levels. You should most certainly see some progress before that though. I would think within a week or two.
Check with your doctor or do some research online as well.
